GitHub CLI Agentic Patterns

Optimized gh commands for AI agent consumption using JSON output and structured field selection.

Core Principle

Always use --json <fields> for machine-readable output. The --jq filter is built-in (no jq installation required).

Pull Request Operations

Check Status

bash
# Get all check statuses
gh pr checks $PR_NUMBER --json name,state,conclusion,detailsUrl

# Filter to failed only
gh pr checks $PR_NUMBER --json name,state,conclusion --jq '.[] | select(.conclusion == "FAILURE")'

Fields: name, state, conclusion, detailsUrl, startedAt, completedAt

PR Details

bash
# Essential PR info
gh pr view $PR_NUMBER --json number,title,state,mergeable,statusCheckRollup

# Full context
gh pr view $PR_NUMBER --json number,title,body,state,author,labels,assignees,reviewDecision,mergeable,statusCheckRollup

Key Fields:

Field Description
mergeable MERGEABLE, CONFLICTING, UNKNOWN
reviewDecision APPROVED, CHANGES_REQUESTED, REVIEW_REQUIRED
statusCheckRollup Array of check statuses

List PRs

bash
# Open PRs
gh pr list --json number,title,author,labels

# PRs by author
gh pr list --author @me --json number,title,state

# PRs needing review
gh pr list --search "review-requested:@me" --json number,title

Workflow Run Operations

Run Details

bash
# Get run status with jobs
gh run view $RUN_ID --json conclusion,status,jobs,createdAt,updatedAt

# List recent runs
gh run list --json databaseId,status,conclusion,name,createdAt -L 10

Status Values: queued, in_progress, completed Conclusion Values: success, failure, cancelled, skipped, neutral

Watch Run Until Completion

bash
# Watch and wait for run to complete (blocking, no timeout needed)
gh run watch $RUN_ID --compact --exit-status

# Find and watch latest run
RUN_ID=$(gh run list -L 1 --json databaseId --jq '.[0].databaseId')
gh run watch $RUN_ID --compact --exit-status

See gh-workflow-monitoring skill for comprehensive workflow watching patterns.

Failed Logs

bash
# Get only failed step logs (most useful for debugging)
gh run view $RUN_ID --log-failed

# Full logs (verbose)
gh run view $RUN_ID --log

Workflow Triggers

bash
# Trigger workflow manually
gh workflow run $WORKFLOW_NAME

# Trigger with inputs
gh workflow run $WORKFLOW_NAME -f param1=value1 -f param2=value2

# List workflows
gh workflow list --json name,state,path

Issue Operations

Issue Details

bash
# Full issue context
gh issue view $ISSUE_NUMBER --json number,title,body,state,labels,assignees,comments

# Minimal
gh issue view $ISSUE_NUMBER --json number,title,state,labels

List Issues

bash
# Open issues
gh issue list --json number,title,labels,assignees

# By label
gh issue list --label "bug" --json number,title

# Assigned to me
gh issue list --assignee @me --json number,title,state

Repository Operations

bash
# Get repo info
gh repo view --json nameWithOwner,defaultBranchRef,description

# Just owner/name
gh repo view --json nameWithOwner --jq '.nameWithOwner'

API Direct Access

For operations not covered by subcommands:

bash
# Get specific data
gh api repos/{owner}/{repo}/actions/runs --jq '.workflow_runs[:5]'

# With pagination
gh api repos/{owner}/{repo}/issues --paginate --jq '.[].number'

Agentic Optimizations

Context Command
CI diagnosis gh pr checks $N --json name,state,conclusion,detailsUrl
Get failure logs gh run view $ID --log-failed
PR merge status gh pr view $N --json mergeable,reviewDecision,statusCheckRollup
Quick issue list gh issue list --json number,title,labels -L 10
Workflow trigger gh workflow run $NAME

Error Handling in Context

Always include fallback for context expressions:

markdown
- PR checks: !`gh pr checks $PR --json name,state,conclusion 2>/dev/null || echo "[]"`
- Run status: !`gh run view $ID --json status,conclusion 2>/dev/null || echo "{}"`
